CAUSES OF CRANIAL NERVES III, IV AND VI PARALYSIS AMONG ETHIOPIAN PATIENTS PRESENTED AT MENELIK II HOSPITAL

Sadik Taju Sherief, Workayehu Kebede

Abstract


Introduction: Causes and clinical features of third, fourth and sixth cranial nerve palsy showed variation among previous studies and cases were analyzed regarding final causal diagnosis.

Method: A cross sectional study was performed among112 patients with third, fourth, and sixth nerve palsy who were consecutively seen at the neuro-ophthalmic clinic of the Ophthalmology Department of Menelik II Hospital. Data was collected prospectively and the etiology and results of ocular examination on each visit were reviewed. A multivariate logistic regression analysis using SPSS version 17.0 was performed to identify independent factors associated with the etiology.

Results: The sixth cranial nerve was affected most frequently (n=60 (53.6%) and head trauma (n=48 (42.9%) was the most common etiology. The mean age at presentation was 34.3 (± 2.54) years. Involvement of the left eye (p= 0.010) and head trauma (p=0.02) as the etiology were statistically significantly associated with sixth nerve cranial palsy.

Conclusion: Sixth cranial nerve is the commonest affected nerve and head trauma is the main cause of cranial nerve paralysis.
